when you use the command+shift+3 (or 4) to take a screenie, it gives it to you saved on your desktop as a .pdf file. Is there any way to change the default format or should I just open each pic in preview and then export them to .jpg ?

The screenshot format can not be changed. Open in Preview and export as whatever you want.

I find myself holding down the control key (eg. Apple+Shift+Control+3) which will copy the screenshot directly to the clipboard, and then in Preview choosing File > New File from Clipboard and exporting the image.

This might result in better quality...

The cmd-shift-3 and -4 actions just call the program /usr/bin/screencapture with the appropriate args.

You could probably do some clever stuff by (for example) renaming screencapture to something else and making a new perl script called screencapture. Then your perl script can interpret the args (like the output file), call the real screencapture, then post-process the output to convert the file or open it in Preview or whatever.

I actually wrote a command-line program to do basic screen captures to jpeg, and then replaced the original with my version. Unfortunately, my quick hack can't do most of the cool stuff that the real screencapture can do. (So I did the above perl hack to call the real screencapture when mine couldn't handle the arguments.)

Be creative and I'm sure you'll be able to come up with something that suits your needs.

Search for SnapNDrag lets you make any file type and change quality etc.
